Remote video monitoring of non-urban outdoor sites

Abstract

A method of remotely detecting rule violations at an outdoor site according to one aspect of the invention includes installing a self-contained VMU at the outdoor site near ground elevation, including affixing a chassis of the VMU to a permanent mount. The VMU is operated in a low-power standby mode that includes passively monitoring an ambient magnetic field at the outdoor site to detect a disturbance caused by a presence of a substantial ferrous object. In response to a detection of a disturbance in the ambient magnetic field, the VMU exits the low-power standby mode and initiates an active operating mode. The active operating mode includes operating a video camera by the VMU to capture video data; and wirelessly transmitting a signal representing at least a portion of the video data to a computer network. The video data is received by a remote node in the computer network via the computer network, and stored in association with a database record.

Description

REFERENCE TO RELATED APPLICATIONS[0001]This application claims the benefit of U.S. Provisional Application No. 60 / 662,205, filed Mar. 16, 2005 and which is incorporated by reference herein in its entirety.FIELD OF THE INVENTION[0002]This invention generally relates to remote video monitoring and, more particularly, to monitoring of remote outdoor locations (such as trails, boat landings, borders) for detection and video capture of potentially unauthorized activities, and transmission of captured video sequences to a remote monitoring center for storage and analysis.BACKGROUND OF THE INVENTION[0003]Monitoring of activity to ensure laws are abided by, such as protecting private property from trespassers or policing proper use of natural resources, at remote sites can be manpower-intensive. Having an enforcement officer present at the appropriate time and place to prevent, recognize, and cite an infraction is unlikely for many reasons. For example, to place a conservation officer or se...

AI Technical Summary

Benefits of technology

[0011]Aspects of the invention are directed to systems deployable to one or more remote locations to detect and monitor certain events or conditions, capture video of activities of interest, and transmit captured video over a computer network such as the Internet, for example, to an off-site database that stores and organizes captured videos. Preferably, captured videos are associated with the corresponding locations where the videos were captured. To reduce the manpower needed to review and analyze the events captured on video, the system can optionally perform video image analysis to identify vehicles, certain activities, and rule infractions. The videos and related data can be made available to authorized individuals for retrieval and reviewing over a computer network.

Problems solved by technology

Monitoring of activity to ensure laws are abided by, such as protecting private property from trespassers or policing proper use of natural resources, at remote sites can be manpower-intensive.

For example, to place a conservation officer or security guard at an access point to monitor lawful access to land and appropriate usage of resources would require at least $120,000 per year per location, and local governments and private organizations or landowners simply do not have the financial and other necessary resources to staff their remote sites around-the-clock.

Also, it is generally understood that lawfulness of conduct is greatly affected by the presence or absence of an enforcement officer.

Thus, in the usual instance when an enforcement officer is absent, unlawful activity is much more likely to take place and go un-checked.

The use of volunteers or interns in lieu of enforcement officers is often ineffective as a deterrent to unlawful activity as the volunteers and interns lack the authority to issue citations to infractions.

These types of technologies are not well-suited to monitoring remote locations, such as in rural outdoor sites in which electrical power and communications infrastructure is not present or readily accessible.

For instance, conventional video cameras have significant power requirements such that mains power is necessary at the camera locations.

Conventional solutions for protecting the remote-mounted cameras from vandalism, such as mounting the cameras 18 feet or more above the ground is costly without the ability to use existing structures and wiring.

Deploying these systems at or near ground level (for example, such that the camera is between 1 and 5 feet from an elevation of a road or trail) or in remote locations to capture infractions only viewable near the ground would quickly render damage to these systems by those individuals whose activity is to be captured at a location where there are no other personnel in the vicinity.

Also, conventional camera housings are typically not hardened to the area of deployment.

The use of hidden or unobtrusively-placed video cameras limits the camera's ability to capture critical identifying information about the subject being monitored, such as a license plate number or boat registration ID.

Moreover, hidden cameras do not provide a deterrent effect for unlawful behavior, which is desirable in some cases.

As described above, due to the lack of power infrastructure, these triggering technologies are not suited for remote non-urban outdoor site monitoring.

These types of motion detectors are generally low-power and respond to detected movement of people and animals in addition to the movement of certain vehicles.

However, IR motion detectors cannot specifically distinguish vehicles from animals.

Therefore, IR motion detectors are not well suited for detecting activities involving vehicles while ignoring other types of activities.

This requirement adds significant design and cost constraints.

It is also quite difficult to use IR sensors and protect them from environmental and vandalism damages.

To date, a practical solution for remote video monitoring of non-urban outdoor sites for specific activities has not been proposed.

In view of the limitations of existing video monitoring technologies described above, as well as other related limitations, the existing remote video monitoring technologies are not readily adaptable to such applications.
